Titan Lab · Drop 01
Size guide
Last updated 31 October 2026
Drop 01 follows Uniqlo Asia sizing. If you know your size in Uniqlo, take the same one here.
If you do not, measure around the fullest part of your chest and find it in the table. That is the only measurement you need.
1. Chest
| Size | Chest, cm | Chest, inches |
|---|---|---|
| S | 89 – 97 | 35 – 38 |
| M | 97 – 104 | 38 – 41 |
| L | 104 – 112 | 41 – 44 |
| XL | 112 – 120 | 44 – 47 |
| XXL | 120 – 127 | 47 – 50 |
These are body measurements — your chest, not the shirt's. They are Uniqlo's own Asia ranges, which is what "follows Uniqlo sizing" means in practice.
2. If you are between two sizes
Take the larger one. Asian sizing runs smaller than European or American sizing, so if you are used to buying M from a Western brand you may well be an L here. Everything in this drop is a print on a standard fit — none of it is cut slim or oversized on purpose.
3. How to measure
- Put a tape around the fullest part of your chest, under your arms and across your shoulder blades.
- Keep it level and snug, not tight. Breathe out normally.
- Read the number and find it in the table.
No tape? Lay a T-shirt you already like flat, measure across the chest from armpit to armpit, and double it. That gives you roughly the garment's chest — a comfortable fit is usually a few centimetres more than your own chest measurement.
4. The cap
One size. It is a dad hat with an adjustable strap at the back, which is the whole point of the strap — there is nothing to choose.
5. The tank
Piece 02 is a muscle tank, so it is sleeveless and cut away at the armhole. Take your normal size: the chest table above still applies.
6. One thing we will add
The table above tells you which size to pick. It does not tell you the finished garment's own measurements — body length, shoulder, armhole — because those belong to the specific blank, and Titan Lab has not confirmed the blank yet. Once it is chosen, its measured flat dimensions go here.
If you want to be certain before you pay, say so when we message you and we will measure a sample and send you the numbers. Nobody should be guessing with a printed garment that cannot be resold in another size.
